Introduction to what terraform is.

An explanation of how to install terraform on Windows / MacOS / Linux

An alternative installation procedure using Vagrant. This will allow you to use exactly the same setup I have!

How to use variables in terraform

A demo of how to use variables in terraform

Provision software on your instance using chef / ansible / puppet / shell scripts.

A demo to show you how to provision software using a shell script

In this demo I'll show you how to use WinRM to provision a Windows Server

Using outputs in terraform you can output information on screen

A demo showing how outputs work

The terraform.tfstate can be stored remotely. This helps collaboration when using Terraform within a team. 

This demo shows how to store the remote terraform state in an S3 bucket. By changing a few flags you can also use it to save it to a consul cluster.

You can use datasources to retrieve external information like AWS IP addresses, AMI IDs, and so on.

A demo using the AWS Region IP ranges to create a security group that only allows access from eu-west-1 and eu-central-1 in AWS.

You can use a template provider in terraform to render templates into strings

There's more than just AWS in terraform. An overview of other providers.

An overview on how to use modules in terraform

A demo showing you how to use external modules. This demo will launch a full consul cluster using an external terraform module

An overview of useful terraform commands

A demo of a few useful terraform commands, including terraform show, terraform graph, terraform import, terraform taint, terraform untaint

An introduction to AWS VPCs (Virtual Private Cloud) - Part 1

An introduction to AWS VPCs (Virtual Private Cloud) - Part 2

An introduction to AWS VPCs (Virtual Private Cloud) - Part 3

A demo showing you how to launch a VPC with an internet gateway and a NAT gateway

Now that we have created our VPC, we can launch EC2 instances in the VPC

This is a demo showing you how to launch instances within a VPC

Test your knowledge!

This lecture shows you how to use EBS (Elastic Block Storage) with an instance

This demo shows you how to attach EBS volumes to EC2 instances

Userdata can be used to execute commands at launch time

In this demo userdata will be used to format and mount an EBS volume if no filesystem is present. This way EBS volumes can be persisted in an automated way when the instance needs replacement.

This lecture explains the difference between private static IPs, EIPs and DNS (Route53)

This demo shows how to use Route53 to create DNS zones in AWS

This lecture explains how to spin up an RDS (relational database service) instance with terraform on AWS

In this demo I will spin up an RDS instance (using RDS subnets, RDS parameter groups, and security groups) and will connect from an EC2 instance to MariaDB..

IAM stands for Identity & Access Management. In this lecture I explain the different possibilities for access management. I explain users, groups, policies, and roles.

In this demo I create a group with an AWS group policy and attach it to a user.

IAM roles can be used to assume (temporary) access. In this lecture I explain how this works.

IAM roles can be used to assume (temporary) access. In this lecture I show you how to attach a role to an EC2 instance that will give permissions to read/write to an S3 bucket.

A lecture explaining how to setup autoscaling in AWS using terraform

A demo of autoscaling using terraform on AWS

Introduction into Elastic Load Balancers and Application Load Balancers in AWS

This lecture explains how to use ELBs in terraform with a static list of instances and an autoscaling group

A demo showing how to use terraform with an ELB together with autoscaling

An introduction of how the Application Load Balancer (ALB) works in terraform

ElasticBeanstalk (AWS's PaaS solution) setup using Terraform

ElasticBeanstalk (AWS's PaaS solution) setup demo using Terraform

Test your knowledge!

With packer AMIs can be created that can be used to launch an EC2 instance.

Packer can be integrated with terraform. This workflow shows how to create a workflow where packer creates the AMI and terraform launches the EC2 instance with the correct AMI ID

Where does Terraform fit in the DevOps organization? In this lecture I show you an example workflow with terraform, packer and jenkins

This demo shows a full cycle of an app in github, the building of a custom AMI with packer in Jenkins and the provisioning and deployment with Terraform

Test your knowledge

This lectures gives an introduction of Docker

This lecture explains how to use Docker on AWS using terraform

This lecture shows how to build docker images that can be pushed on ECR

In this demo I show how to push a docker built image to ECR

This lecture explains part I of the setup of ECS using terraform, with autoscaling and IAM roles

This lecture explains part II of the setup of ECS using terraform, with autoscaling, IAM roles, ECS task definitions and ECS Service definitions

This demo shows you how to run the pushed NodeJS app on ECS

In this demo I show you how to run a Jenkins workflow to build docker images, push the image to ECR, and use terraform to update ECS with the latest docker image
